Explains how Earth's climate system changes, the evidence for human influence, and effects of warming on oceans, sea ice, acidity, marine life, and sea level.
Explores how subduction, continental collisions, and crustal forces build mountain belts, from volcanic arcs and the Himalayas to erosion-driven uplift.
An introductory geology lecture explains how fault slip generates seismic waves, how scientists locate and measure earthquakes, and why hazards such as tsunamis occur.
Explore the fascinating world of tides, their causes, and effects on Earth's oceans. Learn about lunar influences, tidal patterns, and coastal impacts in this comprehensive overview.
Marine sediments preserve records of Earth’s climate, tectonics, ocean circulation, and biological history while providing resources such as sand, phosphates, and manganese nodules.
Learn how weathering, transport, deposition, and lithification create sedimentary rocks that preserve evidence of Earth’s environments and past life.
Learn how magma cooling history, mineral composition, and texture classify igneous rocks as intrusive or extrusive formations.
Trace how weathering breaks down rock, soils develop, and erosion and mass wasting move Earth's surface materials.
Explains how stress deforms rocks into folds and faults, and how tectonic compression, erosion, and isostasy build and reshape mountain belts.
Explore how magma composition, temperature, and dissolved gases control volcanic eruptions, from lava flows and volcano types to hazards, intrusive activity, and plate boundaries.
Explore how continental drift became plate tectonics, with evidence, plate boundaries, seafloor spreading, magnetic reversals, and the forces driving plate motion.
Explore how heat, pressure, and metamorphic environments transform rocks, producing distinctive minerals, textures, grades, and rock types.
An introduction to dynamic shorelines, coastal landforms, wave-driven sediment movement, hurricanes, and shoreline stabilization.
Explore shoreline features, coastal processes, erosion, wave-cut landforms, and stabilization through a geology lecture centered on California’s Redwood National Park.
Learn how geologists reconstruct Earth’s history using relative dating principles, fossils, stratigraphic correlation, and radiometric techniques.
